474-476 Waller St, San Francisco, CA 94117

The property at 474-476 Waller Street is a two-story, two-unit multi-family residential building located in Hayes Valley, owned by Alphonse Wu and constructed in 1900. The building has undergone significant renovations and proposed modifications over the years, with the most recent activity focusing on the addition of an Accessory Dwelling Unit (ADU) on the first floor. Two permit applications for this work were submitted in December 2024, following an earlier cancelled attempt in June 2024.

Historical improvements include major renovations in 2010 to the lower unit, featuring kitchen and bathroom relocations and updates costing $50,000, with associated plumbing and electrical work completed. In 2008, similar substantial improvements were made to the second floor, including kitchen and bathroom modifications, with a cost of $35,000 and comprehensive plumbing and electrical upgrades. The building's infrastructure has been maintained with various updates, including a gas furnace replacement in 2010 and electrical system improvements such as a new 60-amp meter box installation.

The property has experienced recurring issues with street cleanliness and maintenance in the surrounding area, as evidenced by multiple 311 calls between 2019 and 2024 regarding garbage, debris, and cleaning needs. While these external maintenance matters do not directly impact the building's condition, they provide context about the immediate neighborhood environment. Recent calls in late 2024 primarily concerned garbage and debris on the street, with some cases requiring intervention from city services. The building's documented history shows consistent maintenance and improvement efforts by the owner, particularly focusing on unit modernization and infrastructure upgrades, with the most recent push being the ADU addition project currently in the permit application stage.
